Has anyone gotten Calva to load the JDK from the red hat language support for Java extension? On a Windows computer without elevated permissions? I tried setting JAVA_HOME using calva.jackInEnv but no luck.

Best is to make sure JAVA_HOME is set and java on the path in the shell that starts VS Code. I’m not a Windows user, but guessing that if you are in a shell with a working Java and launch code from there, it should work. Otherwise, instead of Jack-in, use the Calva command for copying the jack-in command line and use that in a shell. Then connect Calva.
